To (all whom it may concern:

Be it known that I, ROBERT Srsornrnn, a citizen of the United States, and a resident of Pittshur in the county of Allegheny and State of ennsylvania, have invented a new and useful Im rovement in Flexible Connections for Gear ess Motors, of which the following is a specification.

My invention relates to means whereby electric motors and other prime movers may be connected to the driving-,wheels of vehicles ropelled thereby or to other devices; and it relates particularly to means for resiliently opposing relative endwise movement 13 of the propelled and the propelling members.

The ob3ect of my invention is to provide novel, efiicient, and durable means of the character above indicated.

Electric motors that are employed for. the;

propulsion of locomotives and, other. v chielse are frequently mounted upon quillsorf sleeves that surround {the drivin axles and are directly connectedflto the ax cs or drivlog-Wheels, the motors which1 are so applied 2 5 being generally adapted for s ewer speeds of operation than the more usual forms that are connected to the driving-axles by means of speed-reducing gearing.

In each of two other applications, serially.

o numbered 261,672 and 261,673, respectively, andfiled May 22, 905, 1 have set forth means whereby the quills upon which the motors are mounted may be resiliently connected to and supported by the driving-wheels and a cushioning-ring for opposing relative cndwise movement of the motor and the d ri vin gwhecl. My present invention provides resilient coupling means between the quill and the driving-wheel which does not necessarily 4o differ from What is shown in the one or the other of said prior applications, but it com bines with the one or the other coupling, or with a functionall equivalent means, a more; efiicient and dura le means for opposing and.

absorbin relative endwise movement of the quill an wheel, and it is my desire and intention to herein cover generically all substantially equivalent means for effecting this result.

Figure 1 of the accompanying drawings is a view in section of a pbrtion of an electric motor and means for mounting the same in accordance with my invention; and Fig. 2 is specially-formed helical sprin e raliy comprise a plurality o? convolutlons,

no two consecutive turns of which are con- 75 a view in end elevation of a portion of the vehicle wheel that is shown in Fi 1, one of the parts being removed for the sa e of clearness of illustration.

A11 axle 1, that may be the driving-axle'oi a locomotive or other vehicle, is surrounded by a quill 2, to which a rotatable member or armature 3 of an electric motor is ri idly secured. The stationary member or eld= magnet frame 4 of the motor is mounted upon the quill, so as to permit of rotation of the quill by means of a bearing 5, that is sup- 6 5 ported in an end bracket 6 of the frame.

A driving wheel 7 is mounted upon the axle 1 and is provided with aset of annularlydisposed chambers 8, into which project a corresponding set of bosses 9 from radial 7o arms 10 at the end of the quill 2. The bosses 9 may be surrounded by resilient and s 11, that sevcentric, as shown, described, and claimed in appl cation Serial No. 261,6?3, or they may be surrounded by other suitable cushioning 'nieans, whereby the quill may be resiliently corniccted to and supported by the drivingwheel 7.

In the ends of the bosses 9 are recesses 12, from the bottoms of which the free ends of flanged pins 13 project, the pins being pressed or otherwise secured in drilled openings 14, 55 that may extend axially through the bosses.

A corresponding set of flan ed ins 15 are secured in the end walls of t 1e c iambers 8, so that their free ends project toward the pins A helical compression-spring 16 sur- 9 rounds the free ends of the pins 13 and i5 and serves to relieve the other parts from all shocks resnlti from relative axial motion between the quill and the wheel.

lnlo'rder to permit of ready inspection and 1 repair of the arts within the chambers 8, the outer'ends o the chambers may be provided with screw-threaded lates i7, removal of which may be effected by means of a suitable wrench that may be inserted in openings 18 in the outer faces of the plates.

' I claim as my invention- 1. The combination with an axle having a wheel provided with a set of chambers, a quill or sleeve, surrounding the axle and provided with bosses that pro ect into the chambers, and resilient cushioning means that surround the bosses within the chambers, of rethe chamber and at the bottom of the recess, respectively, and a resilient cushioning means silient cushioning means between theends of 9 between the members that is located within the bosses and the wheel.

2. The combination with an axle having a wheel provided with a set of chambers, a quill or sleeve surrounding the axle and provided with bosses that pro ect into the cham bers, and resilient cushioning means that surround the bosses within the chambers, of helical springs located between the ends of the bosses and the wheel, whereby the energy of relative axial motion of the wheel and quill may be absorbed.

3. The combination with an axle and a wheel mounted thereon that is provided with a set of chambers, of a quill or sleeve that surrounds the axle and is provided with recessed bosses that project into the chambers, resilient cushioning means surrounding the bosses within the chambers, sets of corresponding, oppositely-disposed projections at the ends of the chambers and at the bottoms of the recesses, respectively, and resilient means located within the recesses and supported in position by means of the projections.

4. The combination with an axle, a wheel mounted thereon that is provided with a set of chambers, a quill or sleeve surrounding the axle, bosses that project therefrom into the chambers and are provided with recesses, and resilient cushioning means surrounding the bosses within the chambers, of sets of corresponding, oppositcly-disposed projections at the ends of the chambers and at the bottoms of the recesses, respectively, and helical compression-springs that are located within the recesses and surround the projections.

5. The combination with an axle, a wheel mounted thereon that is provided with a set of chambers, a quill or sleeve surrounding the axle, bosses that project therefrom into the chambers and are provided with recesses, and resilient cushioning means surrounding the bosses within the chambers, of sets of corresponding, oppositely-disposed and removable projections at the inner ends of the chambers and at the bottoms of the recesses, respectively, and helical springs that are located within the recesses and surround the projections.
